"Software" is a broad term, but it could certainly be taken to mean something more abstract than that. Sometimes a program written for a different CPU architecture, or not written for any CPU at all, is still recognisably "the same" program. Euclid's algorithm might well be considered "software", but it's very much the same kind of thing as a mathematical function.
